tumor markers for breast cancer

Release time ：Nov-08,2024

Tumor markers for breast cancer commonly include CA 15-3, CEA, and CA 125, which assist physicians in evaluating the disease and monitoring therapeutic outcomes. However, these markers are not definitive diagnostic criteria, as they can also be elevated in other conditions. CA 15-3, a frequently utilized antigen associated with breast cancer, typically has a normal range of 0-28 U/mL. A result outside this range may suggest the presence or recurrence of breast cancer. CEA, or carcinoembryonic antigen, is a broad-spectrum tumor marker with a normal range of 0-5 ng/mL. While elevated CEA levels can be observed in a variety of cancers, it holds certain reference value in the context of breast cancer patients. CA 125, primarily used for the diagnosis and monitoring of ovarian cancer, may also be increased in some cases of breast cancer. It is important to consider that tumor marker results should be interpreted in conjunction with clinical symptoms, physical findings, and other diagnostic tests; they should not be relied upon as the sole basis for diagnosis. Furthermore, benign conditions can also result in elevated tumor markers. Therefore, if tumor markers are found to be abnormal, prompt medical consultation is advised, followed by further examination and treatment under a physician's supervision.
